XDiag: Exact Diagonalization for Quantum Many-Body Systems
Alexander Wietek, Luke Staszewski, Martin Ulaga +6
Exact diagonalization (ED) is a cornerstone technique in quantum many-body physics, enabling precise solutions to the Schrödinger equation for interacting quantum systems. Despite…
Deconfined quantum criticality of nodal -wave superconductivity, Néel order, and charge order on the square lattice at half-filling
Maine Christos, Henry Shackleton, Subir Sachdev +1
We consider a SU(2) lattice gauge theory on the square lattice, with a single fundamental complex fermion and a single fundamental complex boson on each lattice site. Projective sy…
Sign-problem-free effective models of triangular lattice quantum antiferromagnets
Leyna Shackleton, Subir Sachdev
The triangular lattice antiferromagnet with spins and nearest neighbor interactions is known to have long-range antiferromagnetic order, with nearest-neighbor spins at an a…
Conductance and thermopower fluctuations in interacting quantum dots
Leyna Shackleton, Laurel E. Anderson, Philip Kim +1
We model an interacting quantum dot of electrons by a Hamiltonian with random and all-to-all single particle hopping (of r.m.s. strength ) and two-particle interactions (of r.m.…
An exactly solvable dissipative spin liquid
Leyna Shackleton, Mathias S. Scheurer
Exactly solvable Hamiltonians with spin liquid ground states have proven to be extremely useful, not only because they unambiguously demonstrate that these phases can arise in syst…
Anisotropic deconfined criticality in Dirac spin liquids
Leyna Shackleton, Subir Sachdev
We analyze a Higgs transition from a U(1) Dirac spin liquid to a gapless spin liquid. This spin liquid is of relevance to the spin square latt…
Deconfined criticality and a gapless spin liquid in the square lattice antiferromagnet
Leyna Shackleton, Alex Thomson, Subir Sachdev
The theory for the vanishing of Néel order in the spin square lattice antiferromagnet has been the focus of attention for many decades. A consensus appears to have emerged…
Quantum phase transition at non-zero doping in a random - model
Leyna Shackleton, Alexander Wietek, Antoine Georges +1
We present exact diagonalization results on finite clusters of a - model of spin-1/2 electrons with random all-to-all hopping and exchange interactions. We argue that such ra…
Protection of parity-time symmetry in topological many-body systems: non-Hermitian toric code and fracton models
Leyna Shackleton, Mathias S. Scheurer
In the study of -symmetric quantum systems with non-Hermitian perturbations, one of the most important questions is whether eigenvalues stay real or whether…
Spectral form factors of clean and random quantum Ising chains
Nivedita, Leyna Shackleton, Subir Sachdev
We compute the spectral form factor of two integrable quantum-critical many body systems in one spatial dimension. The spectral form factor of the quantum Ising chain is periodic i…
